Name has changed and now owned by Ceasers. We only stayed one night. When we arrived, there are signs stating "No Semi Trucks". We pulled in and found security to verify if it was okay to stay the night. They said RV's are allowed, just no semi trucks. We stayed in the lot furthest from the casino, which is across the street from the race track. There was nobody else there. A bit of highway noise, but not terrible. It was just very hot in July!
Yes, the RV parking is in a Very large lot across from the casino toward the highway with easy access. Casino is a good distance out of town and so a bit of a drive to good grocery and fuel (fuel is there at that exit but at "highway" prices). There is quite a bit of highway noise being so close but security was good and shuttle service to casino was Very regular. Good radio / tv reception and lots to see and do in Indianapolis. Did not visit the casino this time so I have no insight there. Lots of room for Any size RV and people were very receptive and welcoming.
We stayed on a Saturday night and arrived somewhat late so we ended up parking across the street from the racetrack and new casino near the old white tent like building. It was also Kentucky Derby day so the place was packed. There are shuttles that go around all areas of the lots frequently but the walk is not too long either.
